My Domino server actually accept emails for recipients address which do not exist and send them to recipients who have a name very similar.
For example, if I receive email for email@example.com and this email does not exist, he would send it to firstname.lastname@example.org (which exist and looks a bit similar)
Same for my own address email@example.com. If I receive an email for firstname.lastname@example.org without the dot, I would receive it anyway.
I need to disable this
How should I do?
